SAFETY-OLE-vrs.

To all 'whom t may concern.'

Be it known that I, JOSEPH MIRON, citizen of the United States, residing at Wabeno, in the county of Forest and State of Tisconsin, have invented certain new anduseful Improvements in Safety-Clevises, of which the following is a specification. Y

The present invention relates to a safety clevis which embodies novel features of construction whereby a horse or other draft animal can be instantly detached from a vehicle or the like inthe event the horse gets beyond the control of the driver and thereis serious danger of accident.

The Object of tlie invention is the provision of a device of this character which is simple and inexpensive in its construction,

which comprises few and durable parts,

which will not be caused to accidentally release the horse by the usual jolts and jars of a vehicle Or the like, and which can be easily and quickly actuated when necessary and will then act in a positive manner to release the whitiletree engaged bythe clevis.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as willV more fully appear, as the description proceeds, the novel features thereof being pointed out in the appended claims.

V`For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of a safety clevis constructed in accordance with the invention, the said clevis being shown in engagementwith'the whiiiietree in its normal position. Fig. 2 is a top plan view of the clevis, the leaf spring thereof beingk broken away. Fig. 3 is a side elevation showing the clevis with the parts thereof in the posi- Y tion assumed when releasing the whifletree, portions being broken away and shown in section, and Fig. 4 is a front view ofthe clevis. n

' Corresponding and like parts are referred to in the following description and indicated vin all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the inventlon, the numeral 1 designates the body portion of the clevis which is formed witli'a short upper arm 1a and a long lower arm- 1b, some suitable attaching means such as the ring 2 being pro- Speccaton of Letters Patent.

vided at the base of the clevis for use when attaching the same to a vehicle, pieces of farmmachinery, or t-he like. The end of the short arm 1f?L is bifurcatedto receive the reduced rear end of the main lever 3 which is pivoted 'upon a pin 4 connecting the arms of the said bifurcation. The reduced rear end of this lever 3 is formed with a lateral enlargement 3a received within a correspondvingV pocket in one side of the bifurcation and cooperating therewith when the parts are in normal position, ,as indicated in Fig. 1, to prevent the lever Sfrom pulling away from the clevis and relieving the pin 4 of much of the strain which would otherwise be car ried thereby. The forward end of the main lever 3 isbifurcated to receive the flattened upper end of a draft pin 5 which is designed to engage a notch 6 in the forward edge of the whiiietree 7 the lower end of the draft pin being normally received within a socket 8 inthe long arm 1b of the clevis. The flattened upper end of the draft pin 5 is pivoted upon the bolt 9, the said bolt projecting laterally'upon opposite sidesof the main lever 3 and having the releasing lever 10 mounted thereon. This releasing lever is formed in two sections arranged upon opposite sides of the main lever and is pivoted upon the bolt 9v at anintermediate point in the'length thereof, the rear end of the releasing lever being formed with the cams 10a, while the forward end `of the releasing lever is provided with a transverse bar 11 to which the releasing rod or wire 12 is connected. A leaf spring 13 4is secured to thetop of the clevis 1 by some suitable fastening member 14, and this leaf spring normally projects over the main lever 3 so as to bear against the same and hold the parts yieldingly in normal position.

The whifHetree 7 normally bears 'against the draft `-pin 5 in the usual manner and is held against longitudinal kmovement through the clevis by means of the not-ch 6 therein. Should it be desired to release the draft animal, an upward pull is exerted upon the rod 12 so as to pull the forward end of the releasing lever 10 upward and cause the cams 10a at the rear ends thereof to bear upon the top of the whiffletree 7. A continued pull upon the rod or wire 12 then serves to swing the main lever 3 upward against the action of the leaf` spring 13v so as to withdraw the draft pin 5 from the socket 8 and permit the whiiiietree to eov pull through the clevis, as indicated in Fig. 3. By reference to Fig. 3, it will be observed that the flattened upper end of the draft pin 5 is provided at the front thereof with a cam 5a which is engaged by the end of the leaf spring 13 when the draft pin is swung forwardly to admit of the whiflletree pulling through the clevis. As soon as the whiffletree is entirely released from the clevis, the action of t-he leaf spring upon the cam 5a will again spring the draft pin 5 downwardly so that it will enter the socket 8 when the rod or wire 12 is released.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

l. In a device of the character described, the combination of a clevis, a main lever pivoted upon one arm of the clevis, a draft pin carried by the main lever and adapted to engage the opposite arm of the clevis, a whiffletree arranged within the clevis so as to bear against the draft pin, and a releasing lever carried by the main lever and adapted to bear against the whiffletree to move the main lever and withdraw the draft pin from operative position.

2. In a device of the character described, t-he combination of a clevis, a main lever pivoted upon one arm of the clevis, a draft pin pivotally mounted within the main lever and adapted to engage the opposite arm of the clevis, yielding means normally holding the main lever and draft pin in operative position, a whiiiietree received within the clevis, so as to bear against the draft pin, and a releasing lever pivotally mounted upon the main lever at a point between its ends, one end of the releasing lever being formed with a cam portion adapted to bear against the whiffletree to force the main lever outwardly and withdraw the draft pin from operative position.

3. In a device of the character described, the combination of a clevis formed with a long arm and a short arm, a main lever pivotally mounted within the short arm of the clevis, a draft pin pivotally mounted upon the main lever and adapted to engage the long arm of the clevis, the said draft pin being formed with a cam, a leaf spring extending from the main lever so as to hold the same yieldingly in normal position, the end of the leaf spring cooperating wit-h the cam of the draft pin for normally holding the draft pin in such a position as to engage the long arm of the clevis when moved toward the same, a whiflietree received wit-hin the clevis so as to bear against the draft pin, and a releasing lever pivoted upon the main lever and formed with a cam adapted to engage the whilietree to force the main leve-r outwardly and withdraw the draft pin from operative position.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH MIRON.
